Calculate the value of a gold bar if it weighs 70lbs

During which time interval does the object travel approximately 10 meters

Describe the interaction that occurs between two objects with the same electrical charge.

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
